On 1) does it say autonegotiation fail in the terminal? Do the LEDs on the router show that something is connected when you plug in the board? Maybe you could dig a bit deeper into the datasheet and check the contents of the PHY MDIO registers and find out if anything is strange there. You shouldn't need a cross-over cable as the PHY is capable of MDI-X.
